Roughs

Strangely enough, I'm still not finished with the roughs for chapter 1 yet. D: (normally I finish the roughs first before starting a chapter) I was working on page 18 when suddenly, photoshop started acting weird on me. Why? Why does it always happen when you're ACTUALLY working on something? >.< Anyway, it wouldn't work. Just keeps on getting errors before I get to save anything. I swear photoshop hates me.
